Fixed-torque connecting piece anti-knock buffering combined screw

Abstract

The invention discloses a fixed-torque connecting piece anti-knock buffering combined screw. The fixed-torque connecting piece anti-knock buffering combined screw comprises a screw head, a screw rod, a mounting hole, a twisting block, a connecting rod, limiting holes, limiting rods, springs, insertion holes, an elastic gasket and a magnet block, wherein the screw rod is fixedly arranged at the bottom of the screw head, the mounting hole is formed in the center of the top of the screw head, the twisting block is rotatably arranged in the mounting hole, the connecting rod is rotatably arranged in the center of the hole bottom of the mounting hole, the upper end of the connecting rod is rotatably connected with the twisting block, the multiple limiting holes distributed in the radial direction of the screw head are evenly formed in the inner side wall of the mounting hole, the limiting rods are slidably inserted in the limiting holes, and the springs are arranged at the hole bottoms of the limiting holes. Compared with the prior art, the torque of the screw can be fixed and adjusted, the installation requirements of various strength levels can be met, the anti-knock buffering capacity of the screw is improved, the structure is simple, use is convenient, and application and popularization are convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to an anti-seismic buffer combined screw for fixing torque connectors. 【Background technique】 [0002] Fasteners are a type of mechanical parts used for fastening connections and are widely used.

[0002] Fasteners are a type of mechanical parts used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, and other industries. Screws are A common fastener is widely used in machinery, electrical appliances and buildings. It is generally made of metal or plastic and is cylindrical in shape. The surface is engraved with concave and convex grooves called threads. When the existing screws are installed, the screws The torque is not easy to control, if the torque is too small, the connection will not be reliable, and if the torque is too much, it will easily damage other parts. In addition, the existing screws do not have the function of shock resistance and buffering. It is a rigid contact, and it is easy to damage objects or screws. In view of this, it is necessary to propose a screw that can be adjusted to a specific torque and can be shock-resistant and buffered to overcome the above problems
